"select ACPI_VIDEO" cause recursive dependency when "depends on HWMON"
is added.

---build log
drivers/hwmon/Kconfig:6:error: recursive dependency detected!
drivers/hwmon/Kconfig:6: symbol HWMON is selected by EEEPC_LAPTOP
drivers/platform/x86/Kconfig:326: symbol EEEPC_LAPTOP depends on ACPI_VIDEO
drivers/acpi/Kconfig:208: symbol ACPI_VIDEO is selected by ACER_WMI
drivers/platform/x86/Kconfig:173: symbol ACER_WMI depends on HWMON
---

It is not recommended to use "select" for visible symbol, "select" has changed
to "depends on".

This patch depends on "platform/x86: acer-wmi: add fan speed monitoring
for Predator PHN16-71"

This patch should come before the patch adding the "depends on HWMON",
to avoid a bisect ending up with patch 2/3 applied without patch 3/3
applied and thus picking a non building commit.

Also there is a stub defined for the used acpi_video_get_backlight_type()
function when ACPI_VIDEO is not set, so this can use:

        depends on ACPI_VIDEO || ACPI_VIDEO = n

I have changed the order of the patches for this patch to be before
the patch adding the hwmon support and I've updated the depends as
mentioned above while merging this:

Thank you for your patch, I've applied this patch to my review-hans 
branch:
https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/log/?h=review-hans

Note it will show up in my review-hans branch once I've pushed my
local branch there, which might take a while.

Once I've run some tests on this branch the patches there will be
added to the platform-drivers-x86/for-next branch and eventually
will be included in the pdx86 pull-request to Linus for the next
merge-window.

Regards,

Hans
